CHAIR.

SPECIFICATION forming part of Letters Patent No. 555,642, dated March 3, 1896.

Application filed August Z 7; l8 9 5 To all whom it may concern:

Be it known that we, JOHN H. F. EvERs and HERMANN WOERNER, citizens of the United States, and residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Chairs, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to chairs, and particularly to that class known as camp chairs or stools, and the object thereof is to provide a chair of this description which is capable of being folded into the smallest possible space and which is also strong and substantial, and at the same time light and comparatively inexpensive; and with this and other objects in View the invention consists in a chair constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is a side elevation of our improved chair as extended and ready for use; Fig. 2, a similar view showing the chair folded; Fig. 3, an inside view of one of the legs of the chair with its connected devices; Fig. 4, a side View thereof. Fig. 5 is a bottom plan view of the top of the chair, the legs being shown in section; and Fig. 6, a section on the line 6 6 of Fig. 3, a spring which is connected with the leg at this point being omitted.

In the practice of our invention we provide legs A, which are preferably four in number, and each are also preferably segmental in cross-section with the convex side thereof directed outward, and at the upper ends of each leg on the inner surface thereof are formed or secured loops or rings B, as shown in Fig. 5, to which are pivotally secured or hinged thin elastic metal straps C, each of which is secured to a ring D by means of a loop and rivet d, the connection of said metal straps O with the loops B being similarly made by means of pins or rivets b.

Each of the legs of the chair is provided on the inner lower portion thereof with a rod E, which is secured to the leg at e and e, and

- on each of which is a sliding head F, provided with an inwardly-directed shoulder G, and pivotally secured at the upper end of each of the legs and to each side thereof are crossbars H, said cross-bars being secured to the upper ends of the legs by means of plates 71, and said cross-bars at each side are crossed and pivotally connected at K, and the lower ends thereof are pivotally connected with the sliding heads F mounted on the rods E.

As thus constructed it will be seen that the rods H at each of the four sides of the chair constitute a pair of lazy-ton gs or togglelevers, and by means of the pivotal connection thereof with the upper ends of the legs of the chair, as shown in Fig. 3, and with the sliding heads F on the rods E, said legs may be folded or drawn together, as shown in Fig. 2, or expanded, as shown in Fig. 1.

Secured to the inner side of each of the legs, immediately above the upper ends of the rods E, are springs L, which are extended outwardly and downwardly and provided at their lower ends with rings M and on their inner sides with inwardly-directed shoulders or projections N, and the object of these shoulders or projections is to catch under the heads F or the shoulders G formed thereon and to hold said heads in their uppermost or highest position, which will be the position assumed by said heads when the legs of the chair are extended and said chair is ready for use, as shown in Fig. 1.

Connected with each of the rings M is a cord 0, only two of which are shown'in Fig. 1, but four of which are employedone for each of the springs L. These cords are carried upward and passed through the ring D and through the flexible bottom R of the chair and connected with a head or disk P, as clearly shown in Fig. 1.

The seat or bottom R of the chair is composed of any desired flexible material, such as thin leather or textile material, and said seat is secured to the tops of the legs of the chair by means of pins, nails or screws S or in any desired manner.

The thin flexible metal straps C are designed to form a support for the seat, to prevent the over-extension of the legs and the spreading of the chair, and the operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings.

In Fig. 2 the flexible metal straps C and the bottom or seat R of the chair are not shown, said figure being intended to show the form of the chair when the legs are folded together. \Vhenever it is desired to expand the chair for use, as shown in Fig. 1, it is only necessary to expand the legs thereof, drawing them into the position shown in said figure, and when fully expanded in this manner the shoulders or projections N on the springs L will catch under the shoulders G on the heads within the cylindrical body formed by the legs.

A, as will be readily understood, and it will thus be seen that we accomplish theobject of our invention bymeans of a device whichis simple in construction and operation and one which is comparatively inexpensive.

The legs A may be formed of any desired material, but we prefer to form them of wood, and our improved chair may be made as strong as desired, and at the same time very light, so that it may be easily carried by means of a strap or other device.

Our improved chair will befound to be of great use to many classes of people-such as excursionists, travelers and others-and our invention is not limited to the exact form, construction and arrangement of parts shown and described, and we therefore reserve the right to make all such alterations therein and 1. A folding chair, comprising legs with the tops of which are pivotally connected, at each side thereof, cross-bars which are pivotally I connected at their intersections, and the lower ends of which are pivotally connected with sliding heads which are mounted on vertical rods secured to the inner sides of the legs,

and a spring connected with the inner side of each of said legs and adaptedto operate in connection with said heads, and the top of each leg being also provided with a flexible metal band or strap which is pivotally c011- nected therewith and each of which is pivotally connected with a central ring, substantially as shown and described.

2. Afolding chair, comprising legs with the tops of which are pivotally connected, at each side thereof, cross-bars which are pivotally connected at their intersections, and the lower ends of which are pivotally connected with sliding heads which are mounted on vertical rods secured to the inner sides of the legs, and a spring connected with the inner side of each of said legs and adapted to operate in connection withsaid heads,and the top of each legbeing also provided with a flexible metal band or strap which ispivotally connected therewith, and each ofwhich is pivotally connected with a central ring, and cords or.si1ni1ar devices connected with the lower end of said springs and passed upwardly and through said central ringand through the bottom or seat of the'chair, substantially as shown and described.

3. Afolding chair, comprisinglegs with the tops of which are pivotally connected, at each side thereof, cross-bars which are pivotally connected at their intersections, and the lower ends of which are pivotally connected with sliding heads which are mounted on vertical rods secured to the innersides of the legs, and a spring connected with the inner side of each of said legs and adapted to operate in connection with said heads, and the top of each leg being also provided with a flexible metal band or strap which is pivotally connected therewith and each of which is pivotally connected with a central ring, and cords or similar devices connected with the lower end of said springs and passed upwardly through said central ring and through the bottom or seat of the chair, said bottom or seat being composed of flexible material, secured to the legs, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of the subscribing witnesses, this 20th day of August, 1895.
